Scope: This part is the basic standard of EMC (Electromagnetic Compatibility). It deals with immunity testing of electrical and/or electronic equipment in the electromagnetic environment in which they are placed. This standard deals only with conducted phenomena, including immunity tests for equipment connected to public and industrial networks. The purpose of this section is to provide a basis for evaluating the immunity of electrical and electronic equipment when subjected to changes in power frequency. This part applies to electrical and/or electronic equipment connected to a 50Hz power distribution network with a rated line current not exceeding 16A per phase. This section does not apply to electrical and/or electronic equipment connected to the AC 400Hz power distribution network. Testing of equipment for this type of network will be covered in other standards. In general, electrical and electronic equipment is not sensitive to small changes in power frequency. Tests carried out in accordance with this standard are limited to products that are considered sensitive to variations in power frequency due to characteristics such as design, environment and defects. The immunity test level and performance specification required in the specific electromagnetic environment shall be given together in the product, product class or applicable general standard.
